Write an equation in slope-Intercept form from the polnts (-4,-2) and (-3,5)
y = 1/7x
y = 1/7x + 26
y = 7x + 26
x = 7y + 26

Answers

Answer 1

Answer:

y=7x+26

Step-by-step explanation:

First we have to find the slope of the lines.

(-4,-2)      

(-3,5)    

Our slope is going to equal 7

then we take a point and use it to find the equation

y--2=7(x--4)

y+2=7x+28

y=7x+26

Answers

Answer: All Real Number

Step-by-step explanation:

This is a system of equation, and generally, there are three ways to solve:

eliminationsubstitutionaugmented matrix

Here, we are going to use elimination

------------------------------------------------------------------------------------

Given

-2x-y=1

-6x=3y+3

Put them in the same order

-2x-y=1

-6x-3y=3

Multiply 3 on both sides for the first equation

-6x-3y=3

-6x-3y=3

We subtract the first equation from the second equation

0=0

The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.

Answer and Step-by-step explanation:

For this triangle, to find x, we will use the cosine trigonometric function.

cosine functions look like this:

[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]

(The weird looking symbol is called theta, and represents an angle measurement)

Plug in the values into the equation.

cos(42) = [tex]\frac{x}{15}[/tex]

Multiply both sides by 15.

15(cos(42)) = x

Plug into a calculator.

Step-by-step explanation:

Step 1: Define Systems

y = x + 35

y = 8x

Step 2: Solve for x

Substitution

Substitute in y:                                                                                                8x = x + 35[Subtraction Property of Equality] Subtract x on both sides:                      7x = 35[Division Property of Equality] Divide 7 on both sides:                                 x = 5

Use the graph of the polynomial
function to find the factored form of
its related polynomial. Assume it
has no constant factor

Answers

Answer:

The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].

Step-by-step explanation:

According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.

We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:

[tex]a^{2}-b+c = 0[/tex] (2)

[tex]c = -2[/tex] (3)

[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)

The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:

[tex]y = (x-2)\cdot (x+1)[/tex] (5)
